Hi Ahmed,

Based on the provided description I'm not completely sure what exactly is the issue you are facing. Are you truing to get the RadListView selected item on a external button click?
If this your case you could use the approach below:

protected void Button1_Click(object sender, EventArgs e)
    {
        foreach (RadListViewItem item in RadListView3.SelectedItems)
        {
            ImageButton btn= (ImageButton ) item.FindControl("ImageButton2");

        }
    }

I hope this helps.

when try RadListView3.SelectedItems.Count; always = 0
cause that i cant enter loop
ImageButton btn = (ImageButton)item.FindControl("ImageButton2");
                Image1.ImageUrl = btn.ImageUrl;

how can set selecteditem is clicked image ??

Hi Ahmed,

You could set a CommandName for the specific ImageButton and in the RadListView ItemCommand event manually select the item. For example:

protected void RadListView3_ItemCommand(object sender, Telerik.Web.UI.RadListViewCommandEventArgs e)
{
  if (e.CommandName == "CommandName")
  {
     RadListViewDataItem item = e.ListViewItem as RadListViewDataItem;
     item.Selected = true;
  }
 }

I hope this helps.
